And Cain knew his wife; and she conceived, and bore Enoch: and he built a city, and called the name of the city after the name of his son, Enoch.
All Commentaries on Genesis 4:17 Go To Genesis 4
Augustine of Hippo
AD 430
Consider now the text: “And Cain knew his wife, and she conceived, and brought forth Enoch; and he built a city and called the name thereof by the name of his son Enoch.” It does not at all follow from these words that we must believe Cain’s first son was Enoch, as though “Cain knew his wife” must refer to their first intercourse. You have the same expression used of the first father, Adam, but not only in reference to the conception of Cain, who seems to have been his firstborn, since a little later Scripture records, “Adam knew his wife, and she conceived and brought forth a son and called his name Seth.”
